Hi Greg,
What are you trying to do with a postgres blob in ArcGIS? 
-Postgres will be supported for ArcSDE in the 9.3 release of ArcGIS
- you can also try using the Interoperability extension to read/draw
data out of Postgres, or PostGIS on postgres without ArcSDE

Sincerely,
Kasia

... and I am finding some of the software I am using, namely ArcGIS,
doesn't "like" the PostgreSQL 'text' format as it sees it as a Binary
Blob.... so direct links via ODBC, etc can "die.."

What a pity...

One disadvantage is that if you are using MS Access as a front-end via
ODBC / linked tables, you can not do joins on fields set as text (in
queries, etc)

Don't you mean VARCHAR(n) will be slightly slower on UPDATES.
